Answer 2

Problem Statement:

In an animal shelter, there are 6 cats, 7 dogs, and 3 parrots. A total of 43 kg of food was purchased for them. The cats require 16 kg of food, and the dogs require 16 kg more than the cats. We need to determine how much food was purchased for the parrots.

Identifying Extra Information:

To identify the extra information in the problem statement, we need to consider which data is not necessary to solve the problem when the question "How much food is needed for each dog?" is asked.

In this case, the information about the number of cats, the total amount of food purchased, and the specific amount of food for the cats and dogs are not necessary to answer the question about the food needed for each dog. Therefore, these pieces of information can be considered extra.

Revised Problem Statement:

In an animal shelter, there are 6 cats, 7 dogs, and 3 parrots. A total of 43 kg of food was purchased for them. We need to determine how much food was purchased for the parrots.

Solution to the Revised Problem:

To find out how much food was purchased for the parrots, we can subtract the total amount of food needed for the cats and dogs from the total amount of food purchased.

Let's calculate the total amount of food needed for the cats and dogs: - Cats: 6 cats * 16 kg/cat = 96 kg - Dogs: 7 dogs * (16 kg/cat + 16 kg) = 224 kg

Total amount of food needed for cats and dogs = 96 kg + 224 kg = 320 kg

Now, let's calculate the amount of food purchased for the parrots: Total amount of food purchased - Total amount of food needed for cats and dogs = 43 kg - 320 kg = -277 kg

Since the result is negative, it means that no food was purchased specifically for the parrots. Therefore, the amount of food purchased for the parrots is 0 kg.

Revised Question for Problem 180:

To create a question that requires all the given data to answer, we can ask: "What is the total amount of food needed for all the animals in the shelter?"

To solve this revised question, we need to calculate the total amount of food needed for the cats, dogs, and parrots.

Total amount of food needed for cats = 6 cats * 16 kg/cat = 96 kg Total amount of food needed for dogs = 7 dogs * (16 kg/cat + 16 kg) = 224 kg Total amount of food needed for parrots = 0 kg (as no food was purchased specifically for them)

Total amount of food needed for all animals = 96 kg + 224 kg + 0 kg = 320 kg

Therefore, the total amount of food needed for all the animals in the shelter is 320 kg.

Evaluation of the Revised Question:

The revised question, "What is the total amount of food needed for all the animals in the shelter?", is correctly formulated and requires all the given data to answer. It encompasses the information about the number of cats, dogs, and parrots, as well as the specific amount of food needed for the cats and dogs.
